STOVE-LID AND LIFTER.'

SPECIFICATION forming part of Letters Patent No. 266,194, dated October17, 1882.

Application filed August 18, 1882. '(No model.)

To all whom it may concern Be it known that I, Bonner P. PnARsoN,

a stove-lid or cover-plate as to facilitate the molding of the same andlessen the loss .due to imperfect castings, my improvements relating tothe OOHStI'UGliOD of that part of the lid or plate which is adapted forthe reception of a litter.

In the accompanying drawings, Figure l is a sectional view of astove-lid made in accordance with my invention, the lifter beingdetached; Fig. 2, a similar view, showing the lifter in place; and Fig.3, a plan view of the lid.

The ordinary undercut recesses in stove-lids for the reception of thelifters are objectionable on account of the difficulty of molding thesame, and because of the large percentage of loss occasioned by thefailure of the metal in pouring to fill the contracted spaces formed inthe mold in making such undercut recesses.

In carrying out my invention I form in the stove lid or plate a recess,at, having acentral vertically-projecting stud or pin, b, and I form thelifter din the same manner as an ordinary socket-wrench, the socketbeing of such dimensions that it can be readily applied to the stud dinthe direction of the arrow, Fig. 1, there being a slight play of thestud in the socket, so that when the lid is lifted the stud will binditseltin the socket and prevent the lid from falling.

I have shown a square recess, a, and a square stud, but any otherpolygonal form may be adopted, or, in some cases, the recess or stud, orboth, may be circular, the polygonal form being preferred, however, asit prevents the lifter from turning.

It will be seen thatalid or plate constructed in accordance with myinvention can be readily molded, the pattern leaving the sand freely,and no such skill being required as in molding a lid with an undercutgroove. Moreover, the space in the mold for the formation of the studbis of such dimensions thatthc metal will freely enter the same, andloss on account of defective castings is thus materially reduced.

I claim as my invention- A stove lid or plate having therein a recess,a, with a vertically-projecting stud, 1 adapted for the reception of asocketed litter, substantially as set forth.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

ROBERT P. PEARSON.
